About
I'm Haifeng (Kevin) Zhao, an ML leader with 14+ years building ML and AI agent products for search, recommendations, ads ranking, e-commerce, legal, and go-to-market (GTM), including 6+ years managing teams in Silicon Valley. I have a PhD in CS/ML.
I write about AI agents and large language models: how to build products with them, how to make them perform better (fine-tuning, retrieval, evaluation), how different agents and models compare, and how agents are changing R&D and the industry. Many posts here were first published on Medium. I also build Nexus Digest, a daily briefing on AI news, papers and tools.
